I was wondering if anyone could help me out with this. I understand the concept of some transition metals fill their d orbitals before their s orbitals for instance....
Cu= [Ar] 4s1 3d10 (1 unpaired electron)
Cr= [Ar] 4s1 3d5 (6 unpaired electrons)
but then Fe fills [Ar] 4s2 3d6 (4 unpaired electrons)..s orbital first then d
so what confuses me is that all three are transition metals but two of them fill the d orbitals first and then the s orbital (Cu & Cr) while one fills it's s orbital then its d. Is there a systematic way of knowing which transition metals fill their orbitals which way?!!
